About between the paired main frame portion 8, dispose the battery container 15 of accommodating a plurality of batteries 14 of storing electric power.Battery container 15 is fixed in the main frame portion 8.Battery container 15 is configured to it seems from the side with main frame portion 8 overlapping, and main frame portion 8 it seems the central portion of the short transverse that is positioned at battery container 15 from the side.Setting is taken into the wind and be introduced into the import pipe of using in the battery container 14 16 of travelling from the place ahead near the place ahead of battery container 15, head pipe 7, and the rear end of import pipe 16 is connected in the preceding upper lateral part of battery container 15.The inverter case 19 of holding inverter 18 is installed at battery container 15.Inverter 18 is supplied to the electric power that battery 14 stores and produces alternating current.
Fig. 2 is the part enlarged drawing of Fig. 1.As shown in Figure 2,19 lower surfaces that are held in battery container 15 of inverter case are disposed at battery container 15 belows, and are disposed at motor unit housing 9 the place aheads.The outer rear surface of inverter case 19 is being extended downwards from the lower surface rear portion of battery container 15 and is being arranged.Motor unit housing 9 is disposed at battery container 15 rear sides.From these three housings 9 of forward observation, 15,19 o'clock, by being covered by inverter case 19 and battery container 15 near the zone of top than the line A of level by the nadir of inverter case 19 in three housings 9,15,19 spaces 26 that surround and can not seeing.Observe these three housings 9, at 15,19 o'clock from the rear, by being covered by motor unit housing 9 near the zone of below than the line B of level by motor unit housing 9 vertexs in three housings 9,15,19 spaces 26 that surround and can not seeing.Like this, in the spaces 26 that surrounded by three housings 9,15,19, comprise from the front side and observe, observe from rear side the zone that is blocked that all can not see.
And distribution body 27 is disposed in the zone that is blocked like this in the space 26.Specifically, distribution body 27 from the outer rear surface of inverter case 19, namely than the nadir of inverter case 19 near the place ahead and above the outside face of position configuration extend.Again, distribution body 27 in the outside face of motor unit housing 9 than the nadir of inverter case 19 near the top, and extend near the part of the place ahead and below than the vertex of motor unit housing 9.Distribution body 27 is disposed in the zone that is blocked as mentioned above in the space 26, so the user is not easy from front side and rear side near distribution body 27, and the place ahead of distribution body 27 and rear can access three housings 9,15,19 protection.
Otherwise inverter case 19 is disposed at can be from the position in the space between front clad battery housing and the motor unit housing 9, to form such zone that is blocked in motor unit housing 9 the place aheads.Therefore, inverter case 19 can be subjected to the travel wind next from the place ahead.Thereby the heat element that constitutes the part of inverter 18 can access fine cooling.The lower surface of battery container 15 from the place ahead backward direction have a down dip, inverter case 19 is set to from the lower surface of this battery container 15 outstanding downwards.Thereby, can be with the wind that travels that comes from the place ahead along the lower surface of battery container 15 to inverter case 19 guiding, thereby the air-cooling efficiency of inverter case 19 is improved.But, battery container 15 is had a down dip configuration nothing but an example, also can be with the lower surface horizontal arrangement of battery container 15.
Be covered with motor unit housing 9 and inverter case 19 when again, battery container 15 is configured to overlook.Thereby, seeing three housings 9, at 15,19 o'clock from the top, can not observe by three housings 9,15,19 spaces 26 that surround.Thereby, can for example can prevent well that distribution body 27 from being drenched with rain with the top of battery container 15 protection distribution bodies 27.
Below the structure of battery container 15 and motor unit housing 9 and the configuration of distribution body 27 are described in detail.Battery container 15 forms rectangular shape, has lower wall portion 51, rear wall parts 52, upper wall portions 53 and side wall portion 54.Lower wall portion 51 is vertical mutually with rear wall parts 52, is formed with the bight 55 of lower wall portion 51 and rear wall parts 52 formations in the posterior end of battery container 15 one.Bight 55 constitutes the nadir of battery container 15.In addition, bight 55 also can chamfering form arcuation.
On the other hand, motor unit housing 9 has motor resettlement section 31, the retarder resettlement section 32 that holds retarder 22 that holds motor 21 and stockpiles lubricating oil or the food tray of oil coolant 33, and food tray 33 is positioned at 31 belows, motor resettlement section.It seems that 31 sides, motor resettlement section be roughly circle, and retarder resettlement section 32 is set to advance from 31 rear portions, motor resettlement section more backward and stretches more obliquely upward.The vertex of said motor unit housings 9 is positioned at the preceding upper end of retarder resettlement section 32.Again, motor resettlement section 31 is relative with the outer rear surface of above-mentioned inverter case 19.Therefore, it seems from the front side in the outside face of motor unit housing 9 than the nadir of inverter case 19 and to have stipulated the above-mentioned zone of blocking in space 26 by the back and by the part of top, namely it seems part more forward than the vertex of motor unit housing 9 and on the lower from rear side.This part is roughly the outer upper surface of motor resettlement section 31 and the outer front surface of retarder resettlement section 32.The outer upper surface of motor resettlement section 31 it seems it is the circular shape of epirelief from the side, and the outer front surface of retarder resettlement section 32 it seems it is the linearity of advancing and extend more upward in more past rear from the side.The rear portion of the outer upper surface of said motor resettlement section 31 links to each other with the bottom of the outer front surface of retarder resettlement section 32, constitutes the side as a whole with the outer front surface of the outer upper surface of this motor resettlement section 31 and retarder resettlement section 32 and it seems and be V font roughly.
According to this structure, be formed with the side on the top of motor unit housing 9 and be the recess 34 of V font.In motor unit housing 9, dispose motor drive shaft 23, input shaft 24 and output shaft 25 in regular turn from downside.On the other hand, it seems from the side that input shaft 24 is disposed at the position near rear side one side of battery container 15 (namely away from) than the line C1 of direct connection motor drive shaft 23 and output shaft 25.Thereby, it seems from the side, the line C2 that motor drive shaft 23 is connected with output shaft 25 via input shaft 24 is the same as the V oxbow with the outer front surface of the outer upper surface of said motor resettlement section 31 and retarder resettlement section 32.Above-mentioned recess 34 can be formed by means of this axle configuration, also electro-motor 21 and retarder 22 can be in motor unit housing 9, accommodated integrally.
Be provided with the pivot support sector 37 of the leading section that can connect rocking arm 10 disturbingly at the rear portion of retarder resettlement section 32.Be provided with the connecting portion 38 that connection is used to the rear portion of lower frame section 20 in the front portion of motor resettlement section 31.On the outer front surface of retarder resettlement section 32, be provided with the connecting portion 39 that is connected respectively with paired up and down main frame portion 8 up and down discretely.Like this, the part of motor unit housing 9 double as body shells 6 plays a part identically with in the past pin-connected frame, therefore, compares with 9 situations that are held in body shell 6 of motor unit housing, can realize miniaturization and the simplification of car body frame structure.
When the rearward end of main frame portion 8 is connected in connecting portion 39, the bight 55 that forms in the posterior end portion along the battery container 15 of the bearing of trend setting of main frame portion 8 can be disposed in the recess 34.The relative configuration of outer upper surface of the lower wall portion 51 of battery container 15 and retarder resettlement section 32, again, the relative configuration of outer front surface of the rear wall parts 52 of battery container 15 and motor resettlement section 31.Bight 55 is roughly the right angle, recess 34 is similar with it, it seems that the side roughly form the V font, therefore can make lower wall portion 51 suitably near the outer upper surface of retarder resettlement section 32, and with the outer front surface almost parallel configuration of rear wall parts 52 and motor resettlement section 31 and suitably approach with it.
Position after output shaft 25 is disposed at and leans on than bight 55, on the other hand, motor drive shaft 23 is disposed at position more forward than this output shaft 25 and on the lower, thereby is disposed at than the position of bight 55 near the place aheads.Otherwise also we can say, by bight 55 is disposed in the recess 34, bight 55 is positioned at than the position of the motor drive shaft 23 that is contained in motor unit housing 9 near the rear.Like this, utilize recess 34, can make battery container 15 and the compact dimensionsization of motor unit housing 9 integral body on fore-and-aft direction.Again, motor drive shaft 23 is positioned at than the position near belows, the bight 55 of the nadir that constitutes battery container 15, therefore motor 21 can be disposed at relatively than the below.By means of this, can seek to reduce the center of gravity of vehicle.
Below with in the outside wall surface of motor unit housing 9 with the part of lower wall portion 51 relative configurations, namely the part between motor drive shaft 23 and lower wall portion 51 is called " the first relative portion 35 ", with in motor unit housing 9 outside wall surface with the part of rear wall parts 52 relative configurations, namely the part between output shaft 25 and rear wall parts 53 is called " the second relative portion 36 " to describe.Above-mentioned connecting portion 39 is arranged in this second relative portion 36, by means of this, can access above-mentioned action effect.Form the upper wall of motor resettlement sections 31, the antetheca of the second relative portion, 36 formation retarder resettlement sections 32 according to the first relative portion 35 of this example.
The zone that is blocked as mentioned above in the spaces 26 that surrounded by three housings 9,15,19 it seems that the first relative portion 35 and the second relative portion 36 that are roughly the V font stipulate in the side of closely relative configuration respectively by the lower wall portion 51 in the bight 55 of form right angle and rear wall parts 52 and with them.Therefore can do this zone narrow, it can be made the shape with the complexity of V oxbow again.Thereby, can make the approaching distribution body 27 that is disposed in this zone more difficult.And can utilize bight 55 with battery container 15 to be disposed at the methods that are easy to like this in the recess 34 to form narrow and complicated like this space.
Again, in the bottom of battery container 15, more particularly, and near the one of the posterior end of battery container 15, alignment arrangements inverter case 19 and motor unit housing 9.In this example, inverter case 19 and motor unit housing 9 along fore-and-aft direction or above-below direction, be the direction alignment arrangements of the wall of battery container 15.Therefore, distribution body 27 can extended along lower wall portion 51 from the outer rear surface of inverter case 19 and disposing.Thereafter, distribution body 27 is by the space between the relative portion 35 with first of lower wall portion 51, and the terminal board 60 from the first relative portion 51 that is arranged at motor unit housing 9 extends in motor unit housing 9.Like this; though distribution body 27 is by outside the housing; but also by mutual narrow space near formation between the relative portion 35 with first of relative lower wall portion 51, therefore can make the user more difficult near distribution body 27, can carry out fine protection to distribution body 27 again.Again, in the first relative portion 35 and the second relative portion 36 side of configuration inverter case 19, be that the first relative portion 35 of front side arranges terminal board 60, so can shorten the length of distribution body 27.The first relative portion 35 constitutes the outside face of motor resettlement section 31, and the second relative portion 36 constitutes the outside face of retarder resettlement section 32.Motor resettlement section 31 is disposed at the front side, therefore also can avoid the mutual obstruction of distribution body 27 and retarder 22 simply.
Fig. 3 is that the III-III of Fig. 2 is to view.As shown in Figure 3, terminal board 60 is arranged at the inside part of overall width direction in the motor unit housing 9, specifically the central portion of overall width direction.Distribution body 27 comprises that in order to provide U phase, V reach the three plase alternating current of W phase mutually, has U phase line 61, V phase line 62 and W phase line 63.U phase line 61 has from inverter case 19(with reference to Fig. 2) the extended U phase line 61a in outer rear surface and the 2nd U phase line 61b that extend in 31 to the motor resettlement section from the first relative portion of motor unit housing 9, an above-mentioned U phase line 61a and the 2nd U phase line 61b are electrically connected at terminal board 60.Like this, terminal board 60 is the connecting portion that is electrically connected with the distribution body, and each phase line 61～63 set arranges.V phase line 62 has a V phase line 62a and the 2nd V phase line 62b too, and W phase line 63 has a W phase line 63a and the 2nd W phase line 63b too.In this example, distribution body 27 forms by means of screw component 64 face contacts fixing with this structure that is electrically connected with the connecting portion of terminal board 60.But be not limited to this, also can form by the distribution side connecting portion that forms in distribution body 27 ends and the structure of the chimeric combination of terminal board side connecting portion to be electrically connected that forms at terminal board 60.
